If wet braking matters most
Graded A for wet grip, and nothing else that fits is graded higher. Graded B for rolling resistance. EPREL registration 2853258.

The MG MGS5 EV leaves the factory on 215/60 R17 and 225/55 R18 depending on wheel size, and the 215/60 R17 100H XL below is the one most owners are replacing. XL is not optional here; it is what the car was type approved on. The BYD Atto 2 takes the same size.
| Generation | Trim | Wheel | Tyre size | Load index | Speed | Construction | Marking | Pressure |
|---|---|---|---|---|---|---|---|---|
| Current | 17in wheels | 17in | 215/60 R17 | 100 | H | XL | none | see plate |
| Current | 18in wheels | 18in | 225/55 R18 | 102 | V | XL | none | see plate |
Your own placard is the authority. You will find it on the on the driver's door jamb, on the B-pillar. Where it disagrees with this page, it wins. Match or exceed the size, load index, speed rating and construction class it gives, and use its pressure figure rather than anything printed on the tyre.
Both MGS5 EV sizes are XL, and they differ in speed rating as well as size. The 17 inch 215/60 R17 is 100H; the 18 inch 225/55 R18 is 102V, so an H-rated tyre on an 18 inch car would fall short of spec.
The 18 inch tyre is rated to 850 kg and still keeps a sidewall of about 124 mm, deeper than most 18 inch fitments on electric cars. MG's label sheets name Kumho on the 17 inch and Bridgestone on the 18.
How these were chosen. Everything here already clears this vehicle's own load index, speed rating and construction class. Each heading is a question about use rather than a ranking. The whole method.
Graded A for wet grip, and nothing else that fits is graded higher. Graded B for rolling resistance. EPREL registration 2853258.
Graded A for rolling resistance, the best of anything here, and that is the figure that shows on the range display. Graded B for wet grip. EPREL registration 2430887.
Measured at 72 decibels. Graded B for wet grip. EPREL registration 2219505.
Ordering is by the registered label figure, not by anything we think of them.
An efficiency-first summer tyre aimed squarely at range rather than at cornering.
A Korean-built summer tyre that turns up as original equipment more often than its profile suggests, graded A for fuel efficiency.
Designed for electric cars from the ground up rather than adapted from a combustion tyre, and the winner of the 2025 Auto Bild EV tyre test.
Continental's efficiency summer tyre in the sizes heavy electric cars actually use, available in some fitments with the ContiSilent foam liner.
A touring summer tyre built with Bridgestone's Enliten construction, which cuts weight and rolling resistance across the range rather than in one model.
Including the manufacturer's own published figure. Neither source is standing next to your vehicle, which is why the placard still wins.
